Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify plugin installation and versionCheck the installed plugin version in WordPress via wp-admin/plugins.php or inspect the plugin header in wp-content/plugins/custom-pc-builder-lite/custom-pc-builder-lite.php for the Version fieldAffected if The plugin is installed and the Version is 1.0.1 or lower
-
Identify exposed AJAX endpointsInspect the plugin's main PHP file for add_action('wp_ajax_...) calls and check if they include capability checks like current_user_can() before processing sensitive operationsAffected if AJAX actions lack proper capability checks and are accessible to unauthenticated or lower-privilege users
-
Review admin function access controlsSearch the plugin code for admin action handlers (add_action('admin_...')) and verify if they validate user capabilities using functions such as current_user_can() or wp_verify_nonce()Affected if Admin functions process requests without verifying user permissions or nonces
-
Check role-based access control configurationExamine the plugin settings page in WooCommerce > PC Builder or similar for any access control/security level options and verify if they can be bypassed via direct URL accessAffected if Security level settings can be bypassed or are incorrectly applied to user roles
You are affected if the Custom PC Builder Lite for WooCommerce plugin version is 1.0.1 or lower and AJAX/admin endpoints lack proper capability verification or can be accessed without appropriate authorization checks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to the latest plugin version once available and audit role-based access controls; implement proper capability checks and nonce verification on all sensitive AJAX actions and admin functions.
